FLUSHOMETER.

Application 'filed September To all lwhom t may concern.'

Be it known that l, JOHN Rochas, a citizen` of the TJnited States,residing at Devon, in the county of ll ew Haven and State ofConnecticut, have invented certain new and useful lmproveinents invFlushorneters; and l do hereby declare the following to be a full,clear, and exact description ofthe invention, such as will enable othersskilled in the art to which it appertains, to make and use the same.

rlhis invention relates to llushometers, and it consists in certaindetails of construction to be particularly pointed out in the followingspecification.

Referring to the accompanying drawings wherein the saine figures ofreference indicate lilre parts throughout the several views,

Figure 1 represents a closed central sectional view of the ilushometer,brolren view of its discharge pipe and broken view partly in section ofthe supply pipe:

Figure 2 is a similar View showing the device open, and

Figure 8 is a cross sectional View on line 3-3 of Figure 2.

1 represents the casing divided into the three chambers 2, 3, and 4. lnchamber 2 is located the valve actuating plunger 5 having areciprocating movement therein. In chamber 3 is located the flush valve6 communicating with the discharge or flush chamber 4, and also a reliefvalve-presently to be described-coinmunicating with the interior of theplunger. The valve 6 carries the heads 7 and 8 guided in the projections9. rllhe lower head having the taper face 10 adapted to register withthe valve seat 11 formed in the partition 12. The upper head 8 registerswith the relief valve 13 guided on the stationary stem 14. 15 is a seatin the partitions 12 and 12a for said relief valve opening into thepassage 16, which passage connnunieateswith he interior of the plungerthrough the openings 1'4". 18 is a screw spanning the passage 16 toregulate the amount of water entering the plunger during the `llushingoperation.

The cap 19 has the air vent 2O adapted to be closed by the valve 21 ofthe float 22. 23 is a support located in the chamber 4 on which isjournaled the lever 24, whose end 24 is located in the recess 25, formedby the offset 26 of the plunger 5, when 6, 1923.. Serial No. 498,654.

said plunger is raised. The other end of lever 24 contacts with thestein 27 of the flush valve.

The inlet water pipe 28 is connected to the nipple 29 held irnilyagainst the proieetien of the casing by means of itsk head 30 and nut31. The head 30 has the valve seat for the valve 33, which valve is ncrine. ly rept open by the engagement of its stein 34 with the cross bar35 forming an integral part ofthe casing. rlenfiporarily detaching thefiushonieter for repairs will release the valve 33 and the waterpressure will instantly seat the same and thus effeetually shut off thewater.

The inlet valve 33 being normally open while the flushcmeter is attachedto the inlet pipe 28, the compartment 3 will always be filled withwater. Depressing the plunger- 5, Figure 2, will actuate the lever 24 toopen the flush and relief valves, and at the same time carry the end 24aof the lever out of the recess and against the side of the plunger,forcibly holding said plunger in its depressed position through theforce of the water acting against the flush valve 6 engaging theopposite end of the lever 24.

Opening the flush and relief valves will cause the bulk of the water toflow into the chamber 4 and from thence into the extension 36. ln themeantime, a smaller quantity of water is flowing through the port 15into the interior of the plunger 5, gradually filling the saine duringthe flushing operation. Depressing the `plunger 5 will alsoperrnit thefloat 22 to drop on to the pin 37 and uncover the air port 2O to permitthe escape of air as the plunger is filling with water, and said airport will close as soon as the plunger is filled. The flow of water intothe plunger is simply for the purpose of returning it to its normalposition. As soon as the outward nievement of the plunger has broughtits recess 25 in position to receive the end 24a of the lever 24, saidend will be forced therein by the water pressure acting against theopposite end of the lever, and this pressure will also assist inreturning the plunger while the flush valve and relief valves are beingseated. The return of the plunger will uncover the port 38 in thepartition 38a to permit the water in the plunger to empty into theextension 36, as shown in Figure 1.

Having` thus described my invention what I claim is l. A flushometer ofthe character described comprising a casing having three communicatingchambers, a. reciprocating hollow plunger in one chamber having an airvent, a float adapted to close the vent, a Hush and relief valve in thesecond or valve Chamber, said relief valve operatively connected withthe flush valve, a lever located in the third or tlush chamber in touchwith the Hush valve and plunger so that the inward movement of theplunger will actuate the lever to open both of sai-d valves andtemporarily hold the plunger inits inward position yto permit the volumeof water to pass Yfrom the valve chamber into the Hush chamber, whilesmaller volume of water passes through the relief valve into theinterior of the plunger to return the same to its normal position andclose the air vent and permit the inlet water pressure to close bothvalves, and means whereby the water from `the plunger is discharged intothe flush chamber.

2. A iushometer bil the character ldescribed comprising a casingn havinga valve chamber and a flush chamber separated by a partition, flushvalve having its seat located in said partition and opening into theflush chamber, a hollow reciprocating plunger, a lever pivotallysupported in the flush chamber adapted to be actuated by the inwardmovement of the plunger to open the flush valve and also temporarilyhold the plunger in its inward position, a relief valve actuated by theflush valve having its seat in said partition and a passage leadingtherefrom :to the interior of the plunger, an inlet pipe, saidcasingremovably attached thereto, a valve located between the casirngrand inlet pipe, and means whereby said valve is kept in open position bythe casing So that the valve chamber will always be iilled with waterfrom the inlet pipe.

3. A iiushometer of the character described, comprising a casing havingcommunicating chambers, a iush valve, a relief valve connectedtherewith, a hollow plunger, ya head at one end having` an air vent, afloat within the plunger. a support therefor, said ioat having` amovement between its support and head to close and uncover the vent, andmeans whereby the inward movementof the plunger actuates the valves.

4. A. Hushometer ot the character described, comprising va casing havingcommunicating chambers containing respectively a reciprocating plunger,a flush valve, a relief valve connected therewith, and a pivoted lever,the plunger having a recess to'receive one end of the lever, and theother end of the lever adapted to act-uate the flush valve when theplunger is forced inward.

In testimony whereotI l ailix my signature.
